Ive heard maybe like 7 rwhp gain with the combo... What have your guys experiences be...Im going to be installing a Pi intake and was wondering if I will Benefit with the TB and Plenum on top of the intake... I dont want to spend 2-300 hundred dollars for 5 rwhp that im not even gonna notice.

you won't get a big gain but it improved throttle response some...you can find them cheap used if you look.

I had a BBK plenum and throttle body.I thought it was a waste of money.
I really didn't notest much of any gains from the plenum and throttle body
if any.I would spend my money somewhere else.

What mods were installed at the time that you put the combo on your old stang? Were any of the PI pieces on there along with the Plenum? I'm hoping that the plenum/TB combo along with the the PI intake, cams (even heads) will make more of a (positive) difference than without them.

i just installed the trickflow plenum and BBK 70MM throttle body , i havent drivin the car yet because its winter here and the stang is in the garage till spring but ive heard from others that its not a big gain. Just better throttle response. Maybe with the PI parts it will be more beneficial but I wouldnt pay full price for the parts, i got my t/b and plenum combo for 160$ US, its used but like brand new. look around, if u can find a good used deal then do it, but if not spend it elsewhere.

Nice. That's a good deal you got there and hope it works out for you - let us know. Come on, take that beast out - the stangs like cold weather for better breathing! I've had mine quite a bit this winter. Back to the parts/pieces I have been looking, and unfortunately haven't come across a deal like that and will keep looking. If you guys see another deal like come across, fee free to throw it my way.

Upper and lower control are great investment for any mustang. O0
The problem is the stock control arms have too much play in them.
Just stay far far away from the Granatelli control arms because
the Granatelli lower control arms are well known to stap or crack right
in half at the welds. :nonono:

I put on Accufab 75MM TB and Plenum. I noticed I picked up some mph at th etrack and a small amount of ET. If your car is primarily a street car, then you would be better off using mods that come on sooner. I think there are only a handful of mods that are great for street cars in my experience. Longtubes, full exhaust, cams, things like that. Intakes, plenums, TB's things of that nature should be at the end of your mod list. Anything that deals with the intake side is a waste if your still using exhaust manifolds. Its like a funnel, you can fill the one end full, but its only going to drain as fast as the hole will allow. Its just an air pump.

i think it was the big waste of money but i did a 75mm instead of a 70mm but same thing. i would of been better off spending that money on gas. but the reason i regret it so much is cause i paid full price for it new .if you get a used one it probly wont be that bad of an idea anything helps but dont buy new. not worth it

take that money you would have spent on the tb and plenum and put it toward a nitros kit. thats how you make power on these motors besides the pi swap.
